aliasedInterfaceType property
gets the target interface of the type alias if this is an interface type alias or points to another interface type alias.
e.g typedef A = RealInterfaceType typedef B = A
In this case, aliasedInterfaceType will be RealInterfaceType
Implementation
@override
InterfaceType? get aliasedInterfaceType => _getTargetInterfaceType(this);
